1. Vulnerabilities in the old network:
With the Visor network diagram that has been provided, the following vulnerabilities
have been identified to have affected the operations at the remote site (Ma, Song and Li
2017). The identified vulnerabilities are,
i) Presence of T1 bandwidth from the ISP that provides with slow bandwidth.
ii) VPN server that is outdated and only provides network access from home.
iii) Windows 2000 file server that is outdated and does not provide enough security to
the files and documents.
iv) Cisco 2950 switch that offers limited connections to it, eliminating chances of an
upgrade.
v) Presence of a Windows 2000 web server that is outdated and not equipped with
recent technologies to support updates and might result in software or hardware
failures.
vi) Windows 2003 domain controller that is not secure and security patches need to
be installed separately that can again result in network failures.
vii) Presence of Windows SharePoint server that provides with a minimal amount of
security to the files being shared on the platform and does not provide protection
against the latest cyber threats.
viii) Switched off windows automatic updates that keep the computer outdated and low
on security levels.
ix) Windows XP installed on the computers that do not support the latest versions of
software that might be required by the employees to work.
x) No presence of a firewall to maintain the security of the network's entry point.

xi) No presence of cloud for backing up data, instead of the presence of a local
storage system that might get hampered with time and resulting in permanent loss
of data.

1- The Windows Server 2019 has been installed to replace the previously existing servers
such as domain controller, file server, SharePoint server as well as to increase and upgrade
the network that previously existed.
2- DNS Server to allocated Public IP addresses to personal devices of the employees
connecting to the network.
3- DHCP server for the static allocation of IP addresses to the hosts of the company (Lee
2019).
4- To provide internet connectivity of E1 bandwidth replacing the T1 bandwidth with faster
connectivity.
5- Amazon Cloud server and Storage.
6- Email Server for allowing the employees to share files and documents over the emails.
7- Firewall for maintaining the security at the entry points of the network.
8- the main router that gathers the connectivity from the various servers and distributes the
same among the end-user devices.
9- Amazon Web Services that connects the network to the cloud storages for back up of data
as well as provides with other applications to the network.
10- Cisco 4321 switch to replace the 2950 switch for connecting more devices and upgrading
the network.
11- the router that provides the wireless access points with required connectivity from the
main router and servers.
12- Wireless Access point that allows the hosts to get connected to the network.

13- hosts of the various departments installed with Windows 10, switched on automatic
updates and latest antivirus installed to keep the computer updated.
14- workstations of employees.
15- Personal device that employees can connect to the network.
